The invention pertains to a fitting consisting of a tubular body which may be readily installed over the end of a smooth wall conduit and removed therefrom and may be quickly connected to a standard unisex adapter mounted on the end of a hose line to place the conduit and hose line in fluid communication. The fitting includes a positive lock for attaching the fitting to the conduit and a flexible retainer is employed for safety purposes to resist 'blow off'.

Quick connect fitting for smooth wall conduit

A coupling for use with pressurized systems permitting coupling of valved coupling parts even though one of the parts may be under high pressure. An axially reciprocal valve which automatically opens upon the coupling halves being connected is guided within a shell within the pressurized coupling half and a sealed relationship between the valve and shell minimizes the area of valve surfaces exposed to the pressurized medium reducing the axial forces imposed upon the valve toward the closed position. A bleed valve communicating with the valve interior permits valve operation with hydraulic systems in the event of seal leakage.
